IHL stainless steel chemical pump
is a single-stage single-suction cantilever centrifugal pump
, which was upgraded by Green Ring
Company based on the IH pump. Its markings, rated performance points and dimensions are equivalent to the international standard ISO2858-1975 (E). It is an updated product determined by the Ministry of Machinery Industry to replace the F-type corrosion-resistant centrifugal pump.
According to different industries and mines, the sealing method can be selected: external machine seal, internal machine seal, double-end water-cooled machine seal, container type patented machine seal, etc., and different washing schemes can be selected according to requirements.
The following briefly introduces the characteristics of several mechanical seals:
First, single-end built-in machine seal
Features: The spring and moving ring are installed in a sealed box to contact the medium, and can be sealed by the medium pressure in the box. Its advantages are: good stress, good cooling and lubrication conditions, and wide working range.
Outer-type bellows machine seal
Features: The spring and moving ring are installed outside the sealed box without contact with the medium, which is suitable for strong corrosive media, and its working pressure is low.
Third, double-end water-cooled machine seal
Features: There are two end seals. If the primary seal fails, the secondary seal can still be sealed to prevent leakage. Externally supplied circulating water is required to introduce sealing liquid into the sealed cavity for lubrication and cooling, and is used to reduce force deformation and / or thermal deformation under high pressure and / or high temperature.
Fourth, container patented mechanical seal
Features: Used in harsh industrial and mining conditions, such as high viscosity, easy to crystallize, high temperature, strong corrosion, particulate matter-containing media.
